PAL16R4A4MW883B

Programmable Logic Device Pld Overview

The PAL16R4A4MW883B is a high-performance Programmable Array Logic (PAL) device manufactured by Advanced Micro Devices. It belongs to the PAL16R8 family, featuring a 20-pin ceramic dual in-line package (CDIP-20). The device architecture includes 16 inputs and 4 registered outputs, with 64 product terms available for logic implementation. It operates on TTL voltage levels and supports a maximum propagation delay of 4.5 ns, enabling a maximum clock frequency of 222 MHz. Key functional features include register preload for testability and power-up reset for initialization.

Programmable Logic Device Pld Feature Summary

• Registered output architecture with 16 dedicated inputs and 4 I/O lines
• Ultra-fast 4.5 ns maximum propagation delay for high-speed applications
• Supports register preload and power-up reset functions
• Military-grade CDIP-20 ceramic package compliant with MIL-STD-883

Programmable Logic Device Pld Applications

• High-performance digital logic replacement for TTL circuits
• Synchronous state machine implementations requiring registered outputs
• Complex address decoding and control logic in military systems

Programmable Logic Device Pld Part Context

This component is part of the AMD PAL16R8 family, which also includes the PAL16L8, PAL16R8, and PAL16R6 variants. These devices share standard 20-pin pinouts but differ in output configuration (combinatorial vs. registered) and speed grades. The '883B' suffix indicates compliance with the MIL-STD-883 testing standards for microelectronics.

Programmable Logic Device Pld Replacement Considerations

Direct pin-compatible replacements within the same family include the PAL16R4A4M and PAL16R4A4N. For non-military applications, equivalent PLD architectures from other manufacturers may be considered if timing and I/O configurations match.
